I had surgery in August 2010 for Chiari Malformation. My headaches I was having are completely gone, but I have had other problems since then. I have to get injections in the back of my head and neck for pain and am trying medications for vertigo, nausea and dizziness. Are they related to the Chiari? Maybe not, I'm not sure. I do know the surgery got rid of my headaches that were taking me out of my everyday activities. I would do it again even though I have other challenges now.
